    • To verify that the attenuation observed in experiment 3 was indeed due to changes in the NM sample, rather than the windows, an absorption experiment was performed with a hexane sample. The sample cell was observed to retain transparency for about 600 ns after the shock entered the sample. This is 200 ns longer than was observed with a NM sample in experiment 3. showing that the early onset of opacity in experiment 3 was due to changes in the NM sample, and not failure of the cell windows.

    • A hexane experiment was performed, in the unloading configuration, to verify that the irreversible loss of transmission was not due to a failure of the sapphire back window. This experiment, which reached a peak pressure of 16.8 GPa before unloading to about 7.0 GPa. showed that the hexane cell retained transparency for at least 700 ns after the shock reached the sample.

    • The insensitivity of the thermal explosion model to changes in the rate law was demonstrated by repeating the fits to the induction time data using a fitting function derived from a second-order rate law. In this analysis, the extent of reaction was taken into account by allowing the kinetic function to vary with the reactant concentration. These fits yielded activation energies that were almost identical with those calculated from eq 5. In a similar way, fits using autocatalytic rate laws resulted in values for the activation energy that deviated only slightly from the values given above.
